Reyee OS: Premature Release of Resource During Expected Lifetime
CVE-2024-51727 is a high-severity premature release of resource during expected lifetime vulnerability in Reyee OS from Ruijie, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user.

EPSS estimates a 0.53% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
